IMPROVED TRAGE-FASTENING'.

The Schedule referred to in these Letters Patent and making part ofthesame To all whom. it may concern:

Be it 4known that I, GHARnns WZBLAKESLEE, of Watertown, in the county'ofLitchfield and State of Connecticut, have invented a new and usefulImprovenient in Trace-Locks; and I do hereby declare that the followingis 'a full and exact description of the same, reference being had to theaccompanying drawing and to the letterspf reference marked thereon.

This invention consists of an improved construction of trace-lock, thedetails-of which are hereinafter fully set forth. l

In the drawing- Figure 1 representsa plan view;

Figure 2, a central sectional elevation .Figure 3, a plan view'with thecover removed; and

Figure 4, a plan'view of the cover detached.

'lhis lock is composed mainly of three pieces, the piece A forming thelarger part of the device. It is made by swaging orcasting,vas are theother corresponding parts.

'At thesmaller end it is constructed with a slot, a, of proper sizetopass over the head of the bolt in .the end ofthe whiffletree or otherpart. l Y

The other end is larger, and recessed, to adapt it to receive the end ofthe trace or other strap to which it is to be attached'. This recessextends, somewhat narrowed, to near the. extremity of the open slot,,its sides being shownat b b, in iig. 3 ofthe drawing.: In this recessslides the piece B, formed as shown in figs. 1 and 3. Its forward end isslightly notched, to correspond to the round shank of holt or button,over which the lock passes.

The rear end is `formed with a projecting` flange, covering the spindleand spring, and is perihrated lengthwise, to receive the end ofthe saidspring.

'The rod or spindle which holds the spring in place ,y is properlysecured to the bottom of the open slot, or

may forni part of the metal of it.

When in place, one end of the spring rests on the rod c, and against theshoulder d, the other end heilig in the hole g, (figs. 2 and 3.)

The length of this spiral spring is such as to push the slide quite tothe end of the slot.

From theupper side of the slide is a projection, h, passing through thedetachable side i, and allowing the slide to be manipulated in lockingthe device upon its proper button.

Over the whole is placed the detachable' side or. cover t', which iitsdown snugly over all the parts, making the exterior smooth and uniform.

Having thus fully described my invention, v

XVhat I claim as new, and desire to secure-by Letters Patent of theUnited States, is

The described lock, formed of the described part-s, the main part A,with its slot a, recesses, shoulder (t with its spindle c, the slidewith its socket f/ and projection 7:-, and the covert', all constructedand arranged to operate as set fort-h. a

This specification signed and. witnessed this 28th day of may, 1870.
